Guys,
Iv never been EF crew only WW however I do know that there are a lot of crew who do commute on EF. However there is no point in posting up a roster here because the EF rostering system is all based on personal bids. If you are good at the system and understand how it works it is possible to create a roster whereby you do a lot of nightstop trips allowing you to commute with minimum of cost. However you must also be aware that your bids may not always pan out and you could end up spending many a night in a LHR B&B!
When you first join I would very much suggest you rent somewhere near LHR for the first few months until you settle your feet. The last thing you want when you are on your probationary period is to miss trips because of your commute (it can and will happen). Also you will not get your full concessions until you have been employed 12 months so commuting could become very expensive as you only have a limited number of hotline concessions per year!
